Mohammed, that won't work 'cause the taskbar is protected from that.

Yes it is. Button1 hides the taskbar, button2 shows it again.

procedure TForm1.Button1Click(Sender: TObject);
var
   hTaskbar: THandle;
begin
     hTaskbar := FindWindow('Shell_TrayWnd', Nil);
     ShowWindow(hTaskbar, SW_HIDE);
end;

procedure TForm1.Button2Click(Sender: TObject);
var
   hTaskbar: THandle;
begin
     hTaskbar := FindWindow('Shell_TrayWnd', Nil);
     ShowWindow(hTaskbar, SW_SHOWNORMAL);
end;

That is 'hiding' the taskbar, not 'turning on autohide', which I think jchua wants...

Epsylon, I think I see your point although I'm sure jchua is probably just looking for a way to auto-hide the taskbar when his program runs, then (maybe) show it again when it finishes. You're right though, I've found no way of actually turning the "auto-hide" feature on and off.

Hello

 Epsylon, I don't think that's Imposible, I think that can done by SHAppBarMessage API with ABM_SETAUTOHIDEBAR, but I really didn't that, take a look at microsoft site
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/Shell/Messages/ABM_SETAUTOHIDEBAR.asp

and look at the win32 sdk help file for SHAppBarMessage api

It is NOT POSSIBLE!

I've been searching the net for this a year ago and did NOT find a solution.

So then, my solution posted above is the nearest you can get to auto-hiding the taskbar. I think this is a better way anyway, you shouldn't really change the user's settings, just hide & show the taskbar when you want to.

quote from microsoft:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/shellcc/shell/Shell_Int/Taskbar.asp

"
The taskbar supports two display options: Auto Hide and Always On Top. To set these options, the user
must open the taskbar shortcut menu, click Properties, and select or clear the Auto Hide check box or
the Always On Top check box. There is no way to set these options programmatically.

"
you can only make your own shappbar's autohide by using setstate function.
